MACHINE FOR TREATING HIDES AND SKINS.

I SPECIFICATION forming part of Letters Patent No. 257,495, dated May 9, 1882. Application filed November 22, 1881. (No model.) Patented in England September 23, 188], in Belgium November 15, 1881, in France December 7,1881, in Italy December 3!, 1881, in Austria-Hungary January 2, 1882, in Queensland January 26, 188-2, and in New South Wales February 6, 1882.

To all whom it may concern:

Be it known that I, JOHN WILLIAM J ANSON, a subject of the Queen of Great Britain, residing at London, in the county of Middlesex and Kingdom of Great Britain, have invented new and useful Improvements in Machinery for Unhairing, Fleshing, Faring, Shaving, and Setting Hides, Skins, or Pelts, of which the following is a specification.

My invention relates to improvements in machinery for unhairing, fieshin g, pairing, shavin g, and setting hides, skins, or pelts, by means of which both sides of ahidc,skin,or pelt may be worked upon simultaneously; and it consists essentially in the use of two knife-cylinders, with their respective elastic rollers, instead of a single knife-cylinder, as hitherto. I

attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is afront elevation of the machine; Fig. 2, let'tend view of the same Fig. 3, a transverse section on theline 1 2, Fig. 1, showing position of lower roll when in action; and Fig. 4, a plan of the whole as seen from above.

Similar letters refer to similar parts throughout the several views.

A A are the end standards. B is the feeding-table; G, the upper knife-cylinder; D, elastic roll; E, second ornnder knife-cylinder; F, lower elastic roll; G, clips or draw-bar; H, guide-bars for same; I,treadle for raising roll; K,connecting-rod; L, lever; llLcross'shaft; N, counter-lever; (),beari n gfor roll D; P, counterweight; Q, bearing for lower roll, F; R, rod for actuating same; S, crossshaft; T, cranks; U, handlever; V, quadrant; \V, bell-crank lever; X, belt for driving shaft; Y, cross-shaft; Z, rope-wheels.

It will be seen that, whereas the roll D is capable of a vertical motion, the lower or second elastic roll, F, is free to move in a horizontal direction, being hung upon two arms or lovers, Q Q, working upon pins secured in the end standards, A A. Two rods, RR, serve to connect these arms Q Q to two short levers, TT, secured upon a cross-shaft, S, arranged immediately in front of the machine. Motion is imparted to the shaft S by means of a hand-lever,

U, working around a quadrant, V, as shown. By this arrangement the roll F can readily be drawn forward, and so brought into action with the lower knife-cylinder, E, when required.

The draw-bar or clip G is connected by a rope passing around a guide-pulley secured at outer end of guide-bars H (not shown in drawings) with the rope-wheelsZ Z,by which means it is caused to travel in an outward direction, carrying with it the skin or hide to be operated upon. The skin, hide, or pelt first presented between the top knife-cylinder, U, and the clastic roller D passes over this latter. It is then caught between the roller and the knife-cylinderE. The skin is then drawn out by the clips G in the ordinary way, and thus, passing between the two sets of cylinders and rollers, is treated simultaneously on both sides, the hair and fleshings being separated by a shield,over which the tleshin gs are carried.

The cylinders will be furnished with knives of various kinds, according to the requirements of the particular operation to be performed upon the skin,and each cylinder willnot necessarily carry at the same time the same kind of knives, as the two cylinders, while working simultaneously, may be performing different operations.

I would have it also understood that I do not limit myself to the exact details ofconstruction herein set forth and shown, as such'may be varied while rctainin g the essential characteristics of my invention.

Having thus described my invention, what I desire to secure by Letters Patent is- 1. In a machine for unhairing, fieshing, paring, shaving, and setting hides, skins, or pelts, the knife-cylinder E and roller F, in combination with the knife-cylinder C and roller 1), arranged to operate substantially as and for the purposes set forth.

2. In combination with the cylinders O and E, the adjustable rollers D and F and clips G, as set forth.

JOHN WILLIAM JANSON.
